i only had the one attack and that was about 10yrs ago, maybe even more. was in the hospital for 10 days on massive IV drugs - seems a stone got lodged in my bile duct and the whole thing got inflamed and then involved the liver which is where i passed out in the hospital waiting room trying to tell the receptionist (no triage nurse to be found anywhere) that i was pretty sure something was very very wrong.

fun fact: if you absolutely cannot find a medical person no matter what, just pass out in the lobby. there'll be doctors, nurses, and paramedics popping out from behind air molecules!
